Oracle Database Express Edition (XE)
Oracle Database XE is an entry level database available on Windows and Linux operating systems. XE is built with the same code base as Oracle Database 11g Release 2, so scaling XE to other editions can be easily achieved.
Oracle Database XE is a good starter database for DBAs and developers who need a free database for training and deployment. Independent Software Vendors (ISVs) and hardware vendors can freely distribute Oracle Database XE along with their products, thus adding value to their own products.
Educational institutions can freely use Oracle Database XE for their curriculum. The following are the features of Oracle Database 11g Express Edition:
Available on Linux (64-bit) and Windows (32-bit)
Installs using native installers
Fully upgradeable to other Oracle Database 11g editions
